vb.net - cannot copy paste from datagridview -

i have simple blank windows form test project , datagridview , query fill datagridview

in test project. can highlight columns , rows

click ctrl + c

open excel

then click ctrl + v

and data there.

but on program inherited in company have similar data grid view. cannot copy paste

how can identify difference here? check data grid view properties both test project , program inherited. both has same following: 1. read = false 2. copyclipboardmode = enablewithautoheadertext

what else prevent me copy paste value?

in inherited program way copy paste ist double click cell , copy, but. limits me copy 1 cell @ time , instead of multiple cell

please advise?

thank you

here actual frmform.vb sldworks member of solidworks.interop.sldworks

imports solidworks.interop.sldworks  public class frmform     dim app sldworks     public sub setup(app sldworks, arr arraylist)      end sub      private sub btncreate_click(sender object, e eventargs) handles btncreate.click      end sub end class 

i guessing have set multiselect property of datagridview true
